Experiments to measure the ballistic resistance of light weight armour materials normally comprise the determination of the
ballistic limit velocity V50 for a standardized fragment simulating projectile.
However, in order to characterize these materials in more detail, it is of great interest to know the dynamic response of armour
materials at impact.
To this end, high speed photography is used to monitor target behaviour during impact and subsequent perforation in a timeresolved
manner.
Moreover, in the field of personal protection it is of importance to know the maximum temporary indentation for nonpenetrating
projectiles at impact velocities near the critical V50 velocity as a parameter for trauma-effect.
Experiments, making use of a Imacon camera, are described in which materials for light weight armour applications were
screened.
